(SAFETY 3) code, errors will be signalled in almost all cases if
invalid sequence bounding indices are passed to functions defined
by ANSI to operate on sequences.
+ * fixed a bug in the build procedure: documentation of SBCL-specific
+ packages is now preserved and available in the final Lisp image.
* fixed some bugs revealed by Paul Dietz' test suite:
** ARRAY-IN-BOUNDS-P now allows arbitrary integers as arguments,
not just nonnegative fixnums;
** the logical bit-array operators such as BIT-AND now accept an
explicit NIL for their "opt-arg" argument (to indicate a
freshly-consed result bit-array);
+ ** ELT now signals an error on an invalid sequence index in safe
+ code;
planned incompatible changes in 0.7.x:
* (not done yet, but planned:) When the profiling interface settles
